Specification forming part of Letters Patent No. 196,166, dated October16, 1877 application filed August 3, 1877.

To all whom it may concern:

Be it known that I, BETHUNE PERRY, of Albion, in the county of Mendocinoand State of California, have invented a new and useful Improvement inDrawing-Pens, of which the I sponding parts.

The object of this invention is to furnish an improved drawingpen whichshall be simple in construction and convenient and relia ble in use, andwhich will make a broken line instead of a dotted one.

The invention consists in an improved drawing-pen formed by thecombination with each other of the stem, the spindle, the sleeve, theconcaved and notched disks, the spring, and the nuts, as hereinafterfully described.

A is the stem or handle of the pen, which is made of a convenient lengthand size, and upon the side of the lower end of which is formed, or toit is attached, a spindle, B. Upon disks 1) E are concaved, are placedwith their concave sides toward each other, and have radial notchesformed in their edges. The

' sleeve 0 and its disks, nut, and spring D E F' Gr are kept in placeupon the spindle B by a nut, H, screwed upon a screw-thread out upon theouter end of the said spindle B. The disks D E may be supplied with inkby separating them and putting the ink into the cavity between them; orthe disks may be supplied with ink with a brush without taking themapart.

With this construction, by tightening the nut H, so as to prevent thesleeve 0 and its attachments from revolving, the pen will make acontinuous line, and by loosening the said nut H, so as to allow thesleeve 0 and its attachments to revolve, the pen will make a brokenline. The stem or handle A should be made with a bend or ofiset initslower part, so as to bring the body of said handle directly over theedges of the disks D E.

Having thus described my invention, I claim as new and desire to secureby Letters Pat. ent

An improved drawing-pen, consisting of the stem A, the spindle B, thesleeve 0, the 0011- caved and notched disks D E, the spring G, and

the nuts F H, substantially as herein shown and described.
